Title: Stop-weld paste composition and method for producing aluminium tube-in-sheet utilising the same
IPC: B23K20/18
Filed: 1975-05-05
Abstract: 1460138 Stop weld materials; making heat exchangers SHOWA ALUMINIUM KK 5 May 1975 [13 May 1974] 18799/75 Headings B3M and B3A A stop-weld material for use in forming an expanded aluminium assembly, e.g. a refrigerator evaporator, provides a corrosion inhibiting layer within the assembly, and comprises boron nitride, bentonite, finely divided zinc and the balance carrier. The ranges of constituents are; boron nitride 0À2 to 50% (preferably 10 to 40%); bentonite 0À2 to 10% (preferably 1 to 2À5%) and; zinc 5 to 50% (preferably 2 to 25%). Water, together with an organic solvent to act as a drying agent, may be used as the carrier, and a filler selected from talc, titanium oxide, magnesium oxide, zinc oxide, kaolin, aluminium oxide or aluminium hydroxide may be employed. In an example, two A 1100 aluminium sheets 2 and 3 were hot-rolled after printing one with a stop-weld layer 1 of 33% boron nitride 1À5% bentonite, 23À0% finely divided zinc, 3À0% water glass, and the balance water. The sheets were then cold rolled and annealed, and air was forced between the unwelded sheet portions to produce tubular sections 5. To spread the zinc over the insides of the tubular sections, the assembly was heated at 500 C. for 1 hour. The resulting layer 6 had a thickness of 80 micron and a surface zinc concentration of 1À3%.

Abstract: 796,607. Reaping machines. AGROSTROJ JICIN, NARODNI PODNIK, SUCHY, J., and KVAPIL, L. June 29, 1955 [June 29, 1954], No. 18818/55. Class 6(3). A tractor-drawn mower comprises a wheeled frame 1 to which is pivoted, about horizontal pivots 11, a frame 10, the mower-bar 8 being pivoted to the lower end of the frame about a horizontal pivot 9. The mower-bar is mounted on shoes 12 which are adjustable vertically to vary the cutting height. The frame 10 and mower-bar are lifted by a lever 26 pivoted on a shaft 25 to which is also pivoted a plate 24 connected by a link 22, to a lever 16 pivoted on the frame 10. The lever 16 is linked, by members 17, 18, to the mower bar 8. The plate 24 has an abutment 28 engageable by the lever 26 to lift the plate about the pivot 25 and thereby the mower-bar and frame 10 about the pivots 9, 11. A pivoted pawl 31 enters a notch 29 in the plate 24 to retain the lever in this position, the pawl being displaced by a cam 34 integral with the lever when the mower is to be lowered. A spring 36 attached to a standard 35 on the plate 24 counterbalances the weight of the mower.

Abstract: 397,647. Controlling change-speed gearing. ROUMEFORT, R. DE, 32, Rue Le Peletier, Paris. July 4, 1932, No. 18860. Convention date, July 3, 1931. [Class 80 (ii). ] In vehicle change-speed gear control mechanism with a single control lever 3 which operates sliding gears 22 &c. selectively, a member such as 6, Fig. 2, with oppositely extending ramps 7 disengages the engine clutch as required. The ramp member 6 may be secured to the lever 3 either above or below the usual ball support 2 as shown in Fig. 2. A link 12 extending from the clutch control is jointed to two bell cranks 11 turning on fixed pivots 10 and supporting two rollers 8, one adjacent each of the ramps 7. On movement of the lever 3 in either direction to effect a speed change, one or other of the rollers 8 is engaged by a ramp 7 and depressed so that the link 12 is pulled to disengage the clutch. A position of rest of the partially displaced lever 3 with a roller 8 in a notch 24 in a ramp 7 corresponds to a disengaged engine clutch prior to disengagement of the gears. An extreme position of the lever 3 shown in Fig. 4 corresponds to a re-engaged clutch after a completed gear change. As shown in Fig. 5, the ramps 7 may be carried by a sliding striker 20 engaged by the lever 3 instead of by that lever itself.

Abstract: 569,998. Tail-less aircraft. MILES AIRCRAFT, Ltd., and MILES, F. G. Nov. 12, 1943, No. 18883. [Class 4] To counteract the movement of the centre of pressure in a tail-less aeroplane when normally nested landing flaps 4 are brought into use, a symmetrically surfaced plane 1, normally retracted beneath the central trailing margin of the wing is simultaneously projected rearwardly upon arms 3 at an angle of incidence less than that of the main plane. The plane 1 may carry landing wheels 8 and the whole undercarriage may be lowered at the same time as the flaps 4 and plane 1 are projected. Means may be provided for -varying the incidence of of the plane 1 after it has been projected. In an alternative form the plane 1 is projected forwardly from and retracted beneath the leading margin of the wing, its angle of incidence, when projected, being in this case greater than that of the main plane.

Title: Production of metalliferous coatings
Inventor: PERLMAN ROBERT
IPC: B01J19/00
Filed: 1961-05-25
Abstract: In a process for the production of phosphate coatings on an inorganic substrate (glass, ceramic or metals such as Al, Cu, Fe) an organic acid derivative of a metal or a metal salt of a partially esterified phosphorus acid (either of which may be in a complexed form) is deposited under substantially anhydrous conditions from an organic solution, suspension or melt, the deposit being either reacted with a phosphate or phosphoric acid and then heated to produce a melt and volatilize the organic matter, or the original deposit is heated to produce an oxide coating which may be treated with phosphoric acid to give the phosphate coating.  The original deposit may be obtained by dipping, spraying or mechanical spreading. More than one layer may be applied by the processes of this invention.  Phosphates of Co, Mu, Cu, Cr, Fe, Ba, Ca, Zn, Cd, Mo, or Pb may be applied.  The oxide coating may also be treated with CrO3 to give a chromate coating or alkyl borates or titanates to give borate or titanate coatings.ALSO:In a process for the production of an adherent metal oxide, or sulphide, coating on an inorganic substrate (e.g. metal, glass or ceramics) an organic acid derivative of a metal or a metal salt of a partially esterified phosphorus acid (either of which may be in a complexed form) is deposited under substantially anhydrous conditions from an organic solution, suspension or melt on the surface to be coated, the deposit either being chemically converted by reaction with a sulphur containing reactant and then heated to produce a melt and volatilize the organic matter to produce a sulphide coating, or the original deposit is heated to produce an oxide coating after melting and volatilization of organic matter. The conversion reactant may be added with the coating composition or after the coating has been applied to the surface.  The original coating may be applied by dipping, spraying or mechanical spreading, and may contain additions to enhance the dullness of the final coating such as higher aliphatic amines, carboxylic acids or 1-10% of inorganic salts which do not take part in the reactions.  When the coating composition is to be applied to a metal a salt of the base metal may be added to it to improve adhesion of the coating.  The oxide coatings made in accordance with the invention may be treated with e.g. H3PO4 or CrO3, alkyl borates or alkyl titanates to give phosphate, chromate, borate or titanate coatings.  More than one coating may be applied by the method of this invention.
